For those who don't know about INTERCAL, make note that if you don't write "PLEASE" sufficient number of times in the program, the compiler judges the program to be insufficient in politeness.
Also, if you write too much PLEASE, then compiler judges the program as overeager. Both cases cause rejection of the program. The guy who wrote the compiler to this language was very very sick and intelligent.
